hey folks, after some smart answers from a smart bunch of fellas!
basically i bought these pistons from a guy on here a fair while ago, basically i don't know anything about them, and I'm thinking of selling and not sure what they are! brand etc.
i was told they were "brand new small port pistons"
i have measured the pin and its definatly 20mm--> one point to those who guessed small port pistons.
numbers engraved on the top are
11-660-01 0T
STD
here are some pics
any ideas from those in the know?
